(Cl. 254-185) 9 The present invention relates to a winch and more particularly to a winch adapted to be used on ships for actuating derricks and the like.

The main object of the present invention is the provision of a winch of the character described "having means for actuating the lift of the derrick and also for swinging sideways the boom of the derrick.

An important object of the present invention is the provision of a winch of the character described in Which the winch drum for the lift of the derrick is arranged at right angles to the drums for swinging the derrick thereby resulting in a simplification of the rope or cable layout between the winch and the derrick.

Still another important object of the present invention is the provision of a winch arrangement of the character described by which a single operator is able to control both the swinging movement of the boom and the load lifting means of the derrick associated therewith.

Yet another important object of the present incention is the provision of a winch of the character described which provides three forward speeds for the lift drum and one reverse speed for both swing and lift drums.

A further important object of the present invention is the provision of a winch of the character described in which the swing and lift drums are operated independently of one another.

A still further important object of the present invention is the provision of a winch arrangement of the character described in which the swing drums are automatically braked when declutched from the driving means in order to prevent accidental unwinding of said drums.

Still another important object of the present invention is the provision of a winch of the character described provided with a power take-off for connection to a windlass or the like.

Still another important object of the present invention is the provision of a winch of the character described more partcularly adapted for use on small cargo ships for operating the derricks and also the Windlass and to draw the ship alongside a quay.

The foregoing and other important objects of the present invention will become more apparent during the following disclosure and by referring to the drawings in which:

Figure '10 is a diagramatic perspective view of the driving elements of the winch.

Referring now more particularly to the drawings in which like reference characters indicate like elements throughout, reference numeral 11 indicates a base or platform on which is mounted the winch according to the present invention, together with an operators seat 12 and a footrest 13. The winch is provided with a driving engine shown at 14, which may be an electric motor or an internal combustion engine such as a gasoline or a diesel engine. The driving gears are housed in housing 15 and the following controls are accessible at the operators station defined by the seat-12: a control lever 16 for controlling the direction of rotation of the lift drum 17 and niggerhead 18; a control lever 19 for controlling the direction of rotation of the swing drums 20, shown in Figure 2; a speed adjusting lever 21 for controlling the forward speeds of the .liftdrum 17 and niggerhead 18; a hand brake lever 22 for braking the lift drum 17 and a foot brake lever 23 for the niggerhead or warping drum '18, and for the lift drum 17.

Referring to Figure 2, it will be seen that the transmission gears and clutches are mounted on five parallel spaced shafts ,24, '25, '26, 27 and 28; said shafts are parallel to the shaft 29 on which the swing drums 20 are secured and are perpendicular to the shaft 30 on which thelift drum 17 and niggerhead 18 are mounted. The driving shaft 24 is rotated by the motor 14 through a speed reduction box 31 and drives a chain pulley 32 which is connected to the chain pulley 33 by the chain 34. The chain pulley 33 is secured to the shaft 26 which ice thus rotates in the same direction as the driving shaft 24. The gear chain 34 'also meshes with the chain pulley 35 which is freely rotatable on the shaft 25 and turns in a direction opposite to the direction of rotation of the driving shaft '24. A chain pulley 36 is secured to the shaft 26 and drives through gear chain 38 a chain pulley 37 which is mounted for free rotation on the shaft 25. A double clutch unit is mounted on the shaft 25, the female parts 39 and 40 of which are secured to the chain pulley 35 and chain pulley 37 respectively; and the male part 41 of which is keyed to the shaft 25 but is arranged for longitudinal sliding movement thereon to either engage the female part 39 or the female part 40 or to be inneutral position disengaging both said female parts. The male part 41 of the double clutch is controlled through a forked lever arrangement by the control lever 19 shown in Figure l. The forked lever actuating the male part 41 of the double clutch unit is shown at 43 in Figure 3, said forked lever being secured to a shaft 44 which is journalled in the housing 15 and the projecting end of which mounts the control lever 19 as shown in Figure 1.

It will be understood that when the control lever 19 causes the male part 41 to engage with the female part 40, the shaft 25, together with the gear wheel 45 secured thereto, will berotated in the same direction as the driving shaft 24 through the following elements: shaft 24, chain pulley 32, chain 34, chain pulley 33, shaft 26, chain pulley 36, chain 38, chain pulley 37, female part 40 which is rigid with the chain pulley 37, male part 41, shaft 25 and gear wheel 45.

If the male part 41 is shifted into engagement with the female part 39 of the double clutch unit, the shaft 25 and gear wheel 45 will be rotated in a direction opposite to the direction of rotation of the driving shaft 24 through the following elements: driving shaft 24, chain pulley 32, chain 34, chain pulley 35, female part 39, male part 41, shaft 25 and gear wheel 45.

The gear wheel 45 is in meshing engagement with a larger gear wheel 46 secured to an intermediary stud shaft 47, which also mounts a smaller chain pulley 48 in driving connection with the swing shaft 29 through chain 49 and chain pulley 50. Thus it will be apparent that the swing drums 20 may be rotated forwardly or backwardly or may be kept idle. There is only one forward speed and one reverse speed for the swing drums and the latter are completely controlled by the control lever 19 which actuates the double clutch unit 39, 40 and 41. In order to lock the swing drums 20 against rotation when declutched an automatic hydraulic brake system disposed in a housing 51 (see Figure 3) is controlled through a fluid line 52 by a hydraulic actuator 53, the piston head 54 of which is pressed by a finger 55 when the male part 41 of the double clutch unit is in neutral position. The finger 55 is secured to the spindle 44.

The lift drum 17 and warping drum 18 are actuated from the same motor 14 as that used for actuating the swing drums 20. But the drums 17, 18 have three forward speeds and one reverse speed and their operation is completely independent from that of the swing drums 20 The means for actuating the lift drum and warping drum consist of the following elements: a double clutch unit 56, a change speed mechanism 57, and a reverse drive unit 58. I

The double clutch unit 56 has the same construction as the double clutch unit used in conjunction with the swing drums 20. Said double clutch unit 56 comprises a male part 59 keyed to the shaft 26, but slidable thereon for longitudinal axial movement and selectively engageable with two endwise disposed female clutch parts 60 and 61 which are freely revolving on the shaft 26. The female clutch part 60 is used for forward drive and is provided with an elongated sleeve 62 (see Figure 8) on which are secured three gear wheels of decreasing diameters 63, 64 and 65 and respectively meshing with three gear wheels of increasing diameters 66, 67 and 68. The gear wheels 66, 67, and 68 are freely revolving on the tubular shaft 27 and are each provided with a keyway 69 selectively engageable by a radially extending pin 70 which is mounted on a speed selecting rod 71 slidable within the tubular shaft 27. The pin 70 is slidable within a longitudinal slit 72 made in the tubular shaft 27. In the position shown in Figure 8, the pin 70 engages the keyway of the gear wheel 66 whereby the latter rotates the tubular shaft 27 at the fastest forward speed. The tubular shaft 27 is drivingly connected to the shaft 28 through the chain pulley 73, which is secured to the tubular shaft 27, chain 74 and chain pulley 75 which is secured to one end of the shaft 28. The other end of the shaft 28 is provided with a bevelled pinion 76 in meshing engagement with a bevelled gear 77 itself secured to the shaft 30 of the lift drum 17.

From the foregoing it will be seen that when the male part 59 of the double clutch unit 56 is in engagement with the female part 60, the lift drum 17 may be rotated at any one of three forward speeds which are determined by the selected position of the pin 70 controlled by the selector rod 71 through the means of a grooved wheel 78, a fork 78, a rod 79 and the control arm 21 (see Figures 1 and 2). The rod 79 is journalled in and projects outwardly of the housing and the arm 21 is secured to the projecting end thereof so that rotation of the arm 21 will rotate the shaft rod 79 about its own axis to thereby swing the fork 78' in a plane containing the selector rod71. The adjusted position of the control arm 21 is maintained by means of a plunger finger 80 engageable with any one of the recesses 81 made in an arcuate plate 82 which is secured to the side of housing 15.

When the male part 59 of the double clutch unit 56 is in engagement with the female part 61, the lift drum (5 17 and warping 18 are rotated in the reverse direction and at a single speed through the following means: chain pulley 83, secured to the sleeve 84 of the female part 61, gear chain 85 trained on the chain pulley 83 and on a chain pulley 86 which is secured to the tubular shaft 27, chain pulley 73, chain 74, chain pulley 75, shaft 28, pinion 76, bevelled gear 77 and shaft 30.

Figures 6 and 7 show the warping drum and lift drum arrangement. The shaft 30 is journalled in ball bearings 87 at the side of the housing 15 and projects from said housing to be journalled in a sleeve 88 of a stationary disk 89 which is secured to an upright plate member 90, the latter being rigidly connected to a base plate 91 itself secured to the housing 15.

The warping drum 18 or niggerhead is keyed to the shaft 30 by means of a key 92. A brake band 93 is disposed within a cylindrical recess 94 of the warping drum 18 and is mounted on the stationary disk 89. The brake band 93 is of conventional type and is actuated by pressure fluid supplied thereto through tubing 95 which is connected to an actuator piston and cylinder unit 96 operable by the foot pedal 23, as shown in Figure 3. Thus, when the warping drum or niggerhead 18 is declutched, its unwinding movement may be controlled by the foot brake 23, the latter also controlling the unwinding movement of the lift drum 17 when said lift drum is keyed to the shaft 30 as described hereinafter.

A sprocket gear 97 is keyed to the shaft 30 intermediate the lift drum 17 and the support member 90; this sprocket gear 97 serves as a power takeoff for a Windlass or the like.

The lift drum 17 is mounted for free rotation on the shaft 30 but is engageable therewith through the following means: the drum 17 is provided with an end disk 98 which is in face to face contact with a disk 99 which is itself secured to the shaft 30 as shown at 100. Releasable latching means 101 are provided between the disks 98 and 99. Said latching means are shown in more detail in Figure 7 and consist in a cylindrical member 102 threaded in an aperture made in the disk 99 and in which is mounted a plunger 103 normally urged by a spring 104 into locking engagement in a'recess or short bore 105 made in the disk 98 of the liftdrum 17. The outer end face of the sleeve 102 has a V-shaped recess as shown at 106 and the head 107 of the plunger 103 has a complementary V-shaped end face 108 engageable with the end face 106 to allow the plunger 103 to take a locking position. When the plunger is turned through 90", the apex edge 109 of the head 107 will contact the lateral edges 110 of the sleeve 102 so as to maintain the plunger in releasing position.

The lift drum 17 is also provided with an emergency hand brake arrangement comprising a friction band 111 surrounding the disk 98 of the lift drum 17 and secured at one end to a bolt 112 serving as adjusting means and engaging a side plate 113 as shown in Figure l. The other end of the friction band 111 is attached to a side arm 114 integral with the hand brake lever 22 which is pivoted at 115 on the side of the housing 15.

The'housing 15 forms a fluid-tight casing which will normally be filled with lubricating oil in which all the gear elements of the winch will be submerged for minimum wear.

From the foregoing it will be seen that the winch, according to the present invention, is very compact and that a single operator may control a derrick on a cargo ship which is contrary to the usual procedures in which at least three operators are required for controlling the lift drum and the two swing drums; the latter are normally disposed at some distance from each other.

Referring to Figure 1, it is seen that actuation of the lever 19 controls the swing drums as follows: in the neutral middle position of the lever 19, the drums are kept inoperative and when the lever 19 is rotated from side to side the drums are rotated forward or reverse. Similarly, the control lever 16 will control the lift drum 17 and warping 18.

Lever 16 is secured to a shaft 116 (Figures 3 and 4) to which a fork 117 is also secured. Said fork 117 pivotally engages a band 118 which is in slidable engagement with an annular groove 119 made in the male part 59 of the clutch 56.

When the lever 16 is in upright neutral position, the drums 17 and 18 will be kept inoperative, and when lever 16 is pushed forwardly or rearwardly, the drum 17 and 18 will be correspondingly rotated in forward or reversed direction. Finally, the speed control lever 21 is positioned to obtain the desired forward speed of the drums 17 and 18.

When the winch is used to operate some other elements than the derrick with which it is normally associated, the lift drum 17 is declutched by the latching means 102, and the lever 19 is maintained in neutral position, and, therefore, only the sprocket gear 97 and the warping drum 18 are operated and controlled by the speed control lever 21 and the control lever 16.

Normally the winch drum, according to the present invention, is disposed such that the operator faces the derrick; thus the cable wound on the lift drum 17 can be run directly to the base of the boom of the derrick while, due to the fact that the swing drums are at right angles to the lift drum 17, the cables wound thereon can be run directly to opposite sides of the ship and back again to the boom of the derrick whereby said boom may be swung through a maximum angle.

It will be noted that due to the fact that the control and operation of the swing drums is entirely independent from the control and operation of the lift drum, the boom associated with the winch, according to the present invention, can be operated in such a manner that swinging thereof may be effected simultaneously with the lifting of the load whereby operation of the derrick is effected at a much greater speed than if the boom is swung to the desired position before or after the lifting means are operated.

In the drawings and in the foregoing description, the two double clutch units are of the cone type, but it is obvious that other conventional types of double clutch systems may 'be used such as, for instance, the disc type double clutch.

While a preferred embodiment according to the present inventiori has been illustrated and described, it is understood that various modifications may be resorted to without departing from the spirit and scope of the appended claim.

What I claim is:

A winch for operating a derrick having a boom, a load lifting cable carried by said boom and boom swinging cables attached to said boom; said winch comprising a lift drum on which said lifting cable is wound, swing drums disposed at right angles to said lift drum and on which said boom swinging cables are wound, a single driving shaft connected to a single motive power supply and transmission means between said sin'gle driving shaft and said lift drum and swing drums, said transmission means comprising a first shaft connected by transmission means to said sin'gle driving shaft, a first double clutch unit mounted on said first shaft, a second shaft connected by transmission means to one of said drums, means operatively connecting one part of said double clutch unit with said second shaft to rotate said drum in one direction of rotation and additional means operatively connecting a second part of said clutch unit with said second shaft to rotate said second shaft in a direction to cause rotation of said one drum in the other direction of rotation, a third shaft connected by transmission means to the other of said drums, a second double clutch unit mounted on said third shaft and transmission means operatively connecting said first and third shafts and associated with two parts of said second double clutch unit to rotate said third shaft in either one of two directions of rotation to thereby cause corresponding rotation of said other drum, each double clutch unit compris ing a male part keyed to its associated shaft but axially slidable thereon and two female parts spacedly disposed and facing the respective ends of said male part and freely rotatable on said associated shaft, and control lever means associated with said male part to displace the same on its shaft between end positions in which said male part drivingly engages a selected one of said female parts and a neutral position in which said male part is disengaged from both said female parts, said winch further including hydraulic brake means associated with said swing drums and a finger associated with the male part of said double clutch unit associated with said swing drums to operate said hydraulic brake means to lock said swing drums when said double clutch unit is in n'eutral position.
